Well, what can I say? Sins of a Solar Empire is brilliant. 9/10
The gameplay mechanics do take experience to master, but that's all part of what makes the game so wonderful; there are so many aspects of gameplay to take into consideration when you are in a match, such as culture, research topics, and etcetera. If you think that all you have to do to prevail in a match of Sins is to build a thousand ships and spam orbital cannons, you are sorely mistaken.
One thing that appeals to me personally about Sins is the fact that, right from the beginning, you have to meticulously plan out each detail of your empire's expansion, taking into consideration events that could potentially happen hours later.
That planet with only one phase lane leading into enemy territory? Chances are your enemy will eventually try to punch through. You'll need to plan for that.
The world on the other side of the map that's just starting to produce culture? It will spread to your planets quickly. You'll need to plan for that.
That TEC Loyalist player on the other side of the map whose planet pings up for a second with a superweapon alert? You'll especially need to plan for that.
The one and only downside for me about Sins is, and I'm sure this is a common one, there's no campaign! The franchise has gone into a good deal of detail creating a backstory, seriously, there's a whole bunch of story content out there. What I would really like to see is an actual in-game campaign in which you can follow one of the three main empires on their quests within this storyline. Another little want of mine is to have a campaign constructor. That would be amazing. If these things were there, a 10/10 game.
It's pretty much impossible to get bored of Sins, each game turns out differently from the last. But if, however, you somehow manage to get bored, there's but one thing for that: mods. This game has a Star Trek mod, and subsequently has my seal of approval.
This game is amazing. I myself have had endless hours of fun with Sins, and reccommend this entirely to everybody. Get this game right now.
